Ultrasound-assisted percutaneous catheterization of the axillary vein for totally implantable venous access device

Ultrasound-guided, long-axis, in-plane, infraclavicular axillary vein cannulation: A 6-year experience

BACKGROUND

Despite its potential advantages, ultrasound-guided cannulation of the axillary vein in the infraclavicular area is still rarely used as an alternative to other techniques. There are few large series demonstrating the safety and feasibility of this approach.

METHODS

Retrospective analysis of data on patients undergoing ultrasound-guided, long-axis, in-plane infraclavicular axillary vein cannulation for the incidence of complications and the failure rate from two secondary-care hospitals.

RESULTS

The analysis included 710 successful attempts of axillary vein long-axis, in-plane, US-guided cannulation, and 24 (3.3%) failed attempts. We recorded a 96.7% success rate with an overall incidence of complications of 13%, mainly malposition (8.1%). There was one case of pneumothorax (0.14%), five cases of arterial puncture (0.7%), and two cases of brachial plexus injury.

CONCLUSIONS

The US-guided axillary central venous cannulation (CVC) access technique can be undertaken successfully in patients, even in challenging circumstances. Taken together with existing work on the utility and safety of this technique, we suggest that it should be adopted more widely in clinical practice.

Risk factors for failure of subclavian vein catheterization: a retrospective observational study

Background and objectives

The aim of this study was to analyze risk factors for failure of subclavian vein catheterization.

Methods

A retrospective analysis of 1562 patients who underwent subclavian vein puncture performed by the same experienced operator at Peking University Cancer Hospital from January 1, 2016 to January 1, 2019 was conducted. The success or failure of subclavian vein catheterization was registered in all cases. Various patient characteristics, including age, gender, body mass index (BMI), preoperative hemoglobin, preoperative hematocrit, preoperative mean corpuscular hemoglobin concentration (MCHC), preoperative albumin, preoperative serum creatinine, puncture needles from different manufacturers and previous history of subclavian vein catheterization were assessed via univariate and multivariate analyses.

Results

For the included patients, landmark-guided subclavian vein puncture was successful in 1476 cases and unsuccessful in 86 cases (success rate of 94.5%). Successful subclavian vein catheterization was achieved via right and left subclavian vein puncture in 1392 and 84 cases, respectively. In univariate analyses, age and preoperative hemoglobin were associated with failure of subclavian vein catheterization. In a multivariate analysis, aged more than 60 years was a risk factor while the central venous access with Certofix® was associated with an increased rate of success (p-values of 0.001 and 0.015, respectively).

Conclusions

This study has demonstrated that patient aged more than 60 years was a risk factor for failure of subclavian vein catheterization while the central venous access with Certofix® was associated with an increased rate of success.

Right or left? Side selection for a totally implantable vascular access device: a randomised observational study

BACKGROUND

Totally implantable vascular access device (TIVAD)-related complications interfere in the anticancer treatment and increase medical expenses. We examined whether the implantation side of central line TIVADs is associated with the occurrence of thrombotic or occlusion events.

METHODS

We enrolled patients with cancer who required central line TIVADs and randomised them to receive the TIVAD implantation on either the left or right side. The primary endpoint was the occurrence of catheter-related thrombotic or occlusion events.

RESULTS

We randomised 240 patients, of which 235 received TIVAD implantation according to the protocol. In the per-protocol cohort, 117 and 118 patients received implantation on the left and right sides, respectively. Catheter-related thrombotic or occlusion events occurred in 9 (4%) patients, accounting for 0.065 events per 1000 catheter-days. Between the patients with left- and right-sided implantations, the occurrence rates (P=0.333) and the time from catheter implantation to the occurrence of thrombotic or occlusion events (P=0.328) were both similar. In the multivariate analysis, the side of implantation remained unassociated with the occurrence of thrombotic or occlusion events.

CONCLUSIONS

The side of central line TIVAD implantation was not associated with the occurrence of catheter-related thrombotic or occlusion events in patients with cancer.

A comparison of longitudinal and transverse approaches to ultrasound-guided axillary vein cannulation by experienced operators

BACKGROUND

The axillary vein is an easily accessible vessel that can be used for ultrasound-guided central vascular access and offers an alternative to the internal jugular and subclavian veins. The objective of this study was to identify which transducer orientation, longitudinal or transverse, is better for imaging the axillary vein with ultrasound.

METHODS

We analyzed 236 patients who had undergone central venous cannulation of axillary vein in this retrospective study. Patients were divided into two groups, the longitudinal approach group (n=120) and transverse approach group (n=116). Recorded the one-attempt success rate, operation time, arterial puncture rate and pneumothorax rate. We perform chest radiography to confirm pneumothorax on all patients. We compared the one-attempt success rate, operation time, arterial puncture rate and pneumothorax rate between the two groups.

RESULTS

The two groups were comparable with clinical characters of patients. The overall success rates of the longitudinal group and the transverse group were both 100%. The rate of one-attempt success in the longitudinal approach group is higher than the transverse approach group (91.7% vs. 82.8%, P=0.040). The transverse approach group had shorter operation time than the longitudinal group (184.7±8.1 vs. 287.5±19.6 seconds, P=0.000). The two groups had lower postoperative complications. Arterial puncture occurred in 1 of 120 longitudinal and 2 of 116 transverse attempts and this difference was no significant (P=0.541). No pneumothorax occurred in the two groups.

CONCLUSIONS

The longitudinal approach during ultrasound-guided axillary vein cannulation is associated with greater one-attempt success rate compared with the transverse approach by experienced operators. The transverse approach has shorter operation time. The two groups have lower postoperative complications and are comparable with pneumothorax and arterial puncture.

A manikin-based evaluation of a teaching modality for ultrasound-guided infraclavicular longitudinal in-plane axillary vein cannulation in comparison with ultrasound-guided internal jugular vein cannulation: A pilot study

Background and Aims:

Ultrasound (US)-guided infraclavicular approach for axillary vein (AXV) cannulation has gained popularity in the last decade.

Material and Methods:

In this manikin study, we evaluated the feasibility of a training model for teaching AXV cannulation. The learning pattern with this technique was assessed among attending anesthesiologists and residents in training.

Results:

A faster learning pattern was observed for AXV cannulation among the attending anesthesiologists and residents in training, irrespective of their prior experience with US. It was evident that a training modality for this technique could be easily established with a phantom model and that hands-on training motivates trainees to embrace US-based central venous cannulation.

Conclusion:

A teaching model for US-guided infraclavicular longitudinal in-plane AXV cannulation can be established using a phantom model. A focused educational program would result in an appreciable change in preference in embracing US-based cannulation techniques among residents.

Anatomical study of the accessory axillary vein in cadavers: a contribution to the axillary surgical approach

Background

The axillary vein is an important blood vessel that participates in drainage of the upper limb. Some individuals present a second axillary vein (accessory axillary vein), which is an important collateral drainage path.

Objectives

The goal of this study was to determine the incidence of the accessory axillary vein and to describe this vessel’s topography.

Methods

In this study, axillary dissections were carried out on twenty-four (24) human cadavers of both sexes that had been fixed with 10% formaldehyde. The upper limbs of the cadavers were still attached to the bodies and the axillary structures were preserved. Data collection was carried out and the axillary structures of the cadavers were compared.

Results

The incidence of accessory axillary veins was 58.3%, with no significant preference for sex or for side of the body. The accessory axillary vein originated from the lateral brachial vein in 39.28% of cases, from the common brachial vein in 35.71% of cases, and from the deep brachial vein in 25% of cases.

Conclusions

Its high incidence and clinical relevance make the accessory axillary vein important for provision of collateral circulation in the event of traumatic injury to the axillary vein.

Comparison of two ultrasound guided approaches for axillary vein catheterization: a randomized controlled non-inferiority trial

BACKGROUND

Axillary vein catheterization via a distal approach is an alternative to the proximal approach to axillary/subclavian vein catheterization under ultrasound (US) guidance. The aim of this trial was to compare the two approaches.

METHODS

In a randomized single-centre study, all patients requiring central vein catheterization in intensive care or the operating room were randomly assigned to proximal or distal approach groups. If catheterization failed after two attempts using the approach allocated, the non-allocated approach was used. The primary endpoint was the initial success rate of distal to compared with the proximal approach, using a non-inferiority analysis (lower limit 90% CI greater than -8% non-inferiority margin for group difference). The secondary endpoints were: overall success rates, catheter position and complications.

RESULTS

119/122 included patients were analysed (57 and 62 in the proximal and distal axillary approach groups, respectively). Primary success rates for proximal and distal sites were 87.7 and 85.5%, respectively (difference -2.2%, 90% CI [-12.5-8.1%], non-inferiority P=0.18). The proximal and distal overall success rates were 96.5 and 98.4%, respectively (difference -1.9%, 90% CI [-4.9-8.7%], non-inferiority P<0.01). Thrombogenic catheter positions were 7 (12.3%) in proximal approach group vs 19 (31.7%) in the distal approach group (P=0.01). Complications were comparable in the two groups (2 (3.3%) vs 4 (6.5%), P=0.68).

CONCLUSION

In terms of absolute and overall success rates, a distal approach is not non-inferior to a proximal approach. Although associated with a more thrombogenic catheter extremity position, the distal approach can be considered as a rescue alternative after failure of a proximal approach.

Real-time ultrasound-guided infraclavicular axillary vein cannulation: A prospective study in mechanically ventilated critically ill patients

PURPOSE

The main purpose of this study was to define the venipuncture and catheterization success rates and early mechanical complication rates of ultrasound-guided infraclavicular axillary vein cannulation.

MATERIALS AND METHODS

We performed in-plane, real-time, ultrasound-guided infraclavicular axillary vein catheterizations under emergency and nonemergency conditions in mechanically ventilated, critically ill patients.

RESULTS

We performed 202 cannulation attempts. One hundred and twenty-six procedures (62.4%) were performed under emergency conditions. The puncture of the axillary vein was successful in 98.5% of patients, and the entire procedure success rate was 95.1% (95% confidence interval, 91.1%-97.6%). For the majority of patients (84.1%; P<.001, exact test), the venipuncture occurred during the first attempt. We noted a 22.4% overall complication rate, and most of the complications were malpositions (13.4%). We observed 8.5% of cases with potentially serious complications (puncture of the axillary artery and needle contact with the brachial plexus) and 1 case (0.5%) of pneumothorax. The puncture of the axillary artery occurred in 5 (2.5%) patients.

CONCLUSIONS

In-plane, real-time, ultrasound-guided, infraclavicular axillary vein cannulation in mechanically ventilated, critically ill patients is a safe and reliable method of central venous cannulation and can be considered to be a reasonable alternative to other central venous catheterization techniques.

Fast Track ultrasound protocol to detect acute complications after totally implantable venous access device placement

BACKGROUND

The role of ultrasound examination in detection of postprocedure complications from totally implantable venous access devices (TIVAD) placement is still uncertain. In a cohort of 665 cancer outpatients, we assessed a quick ultrasound examination protocol in early detection of mechanical complications of catheterization.

METHODS

Immediately after TIVAD placement, an ultrasound examination and chest radiography were performed to detect hemothorax, pneumothorax, and catheter malposition. The two methods were compared.

RESULTS

Of the 668 catheters inserted, 628 were placed into axillary veins and 40 into internal jugular veins. The ultrasound examination took 2.5 ± 1.1 min. No hemothorax was detected, and neither pneumothorax nor catheter malposition was evident among the 40 internal jugular vein cannulations. Ultrasound and chest radiography examinations of the 628 axillary vein cannulations detected five and four instances of pneumothorax, respectively. Ultrasound detected all six catheter malpositions into the internal jugular vein. However, ultrasound failed to detect two out of three malpositions in the contralateral brachiocephalic vein and one kinking inside the superior vena cava. Without revision surgery, the operating time was 34.1 ± 15.6 min. With revision surgery, the operating time was shorter when ultrasound detected catheter malposition than when chest radiography was used (96.8 ± 12.9 vs. 188.8 ± 10.3 min, p < 0.001).

CONCLUSIONS

Postprocedure ultrasound examination is a quick and sensitive method to detect TIVAD-related pneumothorax. It also precisely detects catheter malposition to internal jugular vein thus reduces time needed for revision surgery while chest radiography remains necessary to confirm catheter final position.

Intravenous electrocardiography helps inexperienced operators to place totally implantable venous access device more accurately

BACKGROUND

Proper tip position is a major determinant of totally implantable venous access device (TIVAD) outcome. The aim of this study is to analyze the potential utilization of intravenous electrocardiography (IV-ECG) to help inexperienced operators for TIVAD placement.

PATIENTS AND METHODS

This is a retrospective, observational, uni-institutional study. 331 patients receiving TIVAD implantation from July 2008 to December 2008 were recruited. In IV-ECG group, IV-ECG was used to help decide catheter tip location and catheter length. In Landmark group, catheter length was decided by surface landmarks. Catheter tip position was confirmed by post-operative supine chest X-ray.

RESULTS

There were 153 patients in IV-ECG group, and 178 patients in Landmark group. No immediate reoperation due to catheter mal-position was noted in IV-ECG group, but it happened in eight patients in Landmark group. In IV-ECG group, 97.3% of the catheter tip located at proper position (within 2 cm from junction of right atrium and superior vena cava, as compared to 88.8% of the tip position in Landmark group was proper. The difference was statistically significant (P < 0.05). There was no complication associated with the use of IV-ECG.

CONCLUSION

IV-ECG is a safe and convenient method to help inexperienced operators placing TIVAD.
